h l A 1 9 which meshes I see I! 1, an

on a shaft 1t carrying a gear wheel 15. The gear wheel engages a pinion 16 on a shaft 17 and thus turns a fourth large gear 18 mounted on this last-named shaft. The gear 18 turns a pinion 19, see Fig. 2, on a shaft 20, the outer end of which projects through a bearing in a bracket 21, and carries an escapement wheel 22 having inclined teeth The gear 12 also engages a pinion 21'- mounted on a central shaft which projects through the front of the frame and carries the minute hand of the clock. The shaft 25 also carries another pinion 26 which meshes with a gear 27 on a shaft 28. This gear 27 transmits motion to a pinion 29 which operates the controlling devices for the hammer 3. On the spindle 2S and turning therewith and with the gear 17 is another pinion 30, see Fig. 2, by means of which motion is transmitted to a large gear wheel 31, which is rigidlj mounted on sleeve This sleeve projects out through the front of the casing and surrounds the shaft 25, and serves to transmit motion to the hour hand. This sleeve turns at one-twelfth the same angular speed as the shaft as is required in clocks of this type. The pinion 30 also meshes with a gear 53, which actuates the controlling devices for the hammer t:-

t will be seen in Fig. 2 of the drawings that the gears 12, 15 and 83 with their associated pinions are all located adjacent the front of the clock frame while the gears 26 and 27 with their associated pinions are located at the back of said frame. Furthermore. the gearing described will be so designed that the sleeve 32 will turn onetwelfth as fast as the shaft The pinion 29 and the gear wheel will be turned faster than said sleeve. The gear wheels and 33 have surfaces which are engaged by springs 29, 33, see Fig. 4, on the frame to hold the gears against free movement. The diameter of the pinion 29 will in practice be made equal to the diameter of the pinion 26, and the diameters of the gears 31 and 33 will likewise be equal.- Furthermore, the gears 29 and 26 will have the same speed, and the gears 31 and 38 the same speed.

The ratchet wheel 22 is controlled by means of an escapement device comprising a lever 3% having lugs 35 located at or near th center of the same and mounted by means of perforations in these lugs to rock upon a pivot pin 36. This lever has its ends bent as shown in Fig. 1, and as it rocks each end will engage the inclined edges of the teeth 23 by turns, permitting the ratchet wheel to move intermittentl in the usual way. This lever 3 will be rigid with a suspension bar 37 having a hook 538 at its lower end to carry a pendulum bob, and the bar 37 will be engaged by a spring 39 to control its movements.

The end of the main shaft 8 may be squared or given some other polygonal shape, as shown at 10, and may be connected rigidly with the inner end of the spring and to the large gear 9 by means of a ratchet #11, so as to enable the spring to be wound up without turning the wheel, and enable the unwinding movement of the spring, causing the shaft to be turned in the opposite direction to carry the ratchet wheel and the large gear 9 with it.

The hammer bars 5 are actuated by means of arms i2 secured to pivoted spindles 13. These hammer bars are made rigid with these pivoted spindles, and the arms 42 are engaged by the teeth of the gear 18, as shown in Fig. 3, the gear rotating counter clockwise, and it will be evident that each tooth lifts the free ends of the bars 12. As the arms slip past the teeth engaging the same the hammer bar will be dropped and the hammer at the end will strike the hell 2. The spindles 1 3 will also be provided with threaded projections on which are screwed adjustable counterweights 11. These counterweights regulate the force with which the hammers 3 and at impinge upon the bell 2. An arm 5, see Fig. 3, with a pin at its end can be employed to lift the hammers 3 and i to throw them out of operation. this arm being actuated by a knob or projection at the back of the clock.

At the top of the frame 1 and extending transversely thereof at both the front and back of the same is arranged a pair of uprights l5, each of which has an inwardlyextending lug to receive a mounting device 46. This mounting device pivotally supports a pair of yokes i7, each :I1'1"llig a rigid downwardly-projccting lug l8. Each of the Yokes is also provided with a counterweight s19, and secured to each lug 48 by means of a screw and slot connection to make the same adjustable is a hanger bar which has projections thereon to engage the hammer bars 5 and prevent them from striking the hell 2, except at the right instant. The hanger bars are shown at 50 and 51, two at the front and two at the back of the frame. the front pair being associated with the hammer 4- and the back pair with the hammer 23. The bars 50 and 51 ac pivoted on the devices 46. The counterweights elf) are preferably in the form of milled nuts mounted upon threaded projections so as to be adjustable.

The hanger bars 51 are shorter than the bars 50. The bars 50 have notched ends 52, see Fig. 3, guided by pins 53. The hanger bars 51 have ring-shaped sections 54 concentric with the pinion 29. The said sections have projections provided with bent-over ends 56, see Fig. 3, the parts 55 and 56 are in substantially horizontal planes. The bars 50 have projections 57.

iii

The portions 56 and 57 for each pair of bars are preferably alined with each other. lVhen the inner end of the portion 56 of one ol. the bars 51 conacis with the portion 57 of the associated her 50, the adjacent hammer har 5 will he arrested heiliore the hammer strikes the hell But when the bars and 51 are swung apart to allow the associated hammer bar 5 to pass hetween the han'nner strikes the hell 2. The bars fill and 51 are actuated hy cams 58 on the shaft 17. These cams are hest seen in Fig. 5 ol? the d awings. The bar 51 has an \uiturned end 55.) on a projection (31. A similar nojectioiii (i1 is carried hy the asst ciated hair 50. The front har 51 at the front of the ole-ch l? zone has a projection 60 which extends upwa rd and toward the Front of the ilraine. These projections are engaged hy the cams to more the one hanger bill to the rear and the other hanger har to the front.

Each hool: (3 1-. has a projection 60 adjacent the pivot (35 for limiting the up ward moreinent 0;!" the hooks G l.

Tl e upper end of each hanger ha r 50 as hest seen in Fig. 9 ol the draw'ngs carries a spring 70. having ends 72 which pass through openings in each bar 50 and orig n. the dish (33, and force it against the end flange oi. the sleeve (32. Between the ends of this dist: is a shoulder which rests against one face of the her and adjacent the shoulder. and a t the opposite face of the h: r 50 is a groove or recess '78 which receives a spring); Te :llS" f-cured to the he?" 50. This shoulder and. this spring 7% hold the her and the sleeve 6'? together. A screw 71 holds the spring '70 in place.

The hers 50 each carry a spring 75 which cxends upward along the lower edge of the nojection S1, and bent in position to he engaged by the cam 58, as shown in Fig. This (loin-bent portion of the spring 75 is engaged hf; a screw 76 to regulate the position thereof. If desired, the spring 75 can he omitted and the part 61 shaped to take its place.

The pinion likewise the hub of the great 33, has projeet'ng bosses 77 which are a; 1 through the gear 29 and the tie gear pass rivets forming gears 29 and 33 rotate.

finals on which the bosses 77 form frlction mounts At the outer ends of sleeves The hollow 'lor sleeves 78. 78 are mounted disks 79 which have slotted (:3 Eli I'l ts whi id througl. the trout and hack of the i) iTOZ'lRlHQ; the et 1- nals or the 35, have reduced sorew-threaded inn .r end hown at ill, and upon these projet snowed sleeves 82.

In operation the n the so as '"i snring 6 will re the sleeve tote end the shalt ine ciuas o8, are lL-(il 6(l tie propel cuslee nrojece and (30 on the front and rear pair of l '"er liillS 50 and 51, to more these liars chard the :front and lack of the frame wort, respectirely, as seen in Figs. 5 and 6 the drawings. Normally these bars will occupy the position shown by the pair at the left of Fig. i, the counterweights 19 being regulated to hold them in such location. In this position the portions 56 and 57 will prevent the hammers 3 and 4: from striking the hell 2. although the gear 18 moves the arms 1-2 to swing the bars 5 outward and allow them to drop back under the influence of their own weight, the portions 56 and 57 arresting these bars 5 before the hammers 3 reach the hell 2.

hen the bars and 51 are in position as shown at the right in Fig. t, the corresponding cam 58 will move the bars to the right together and hold the same in such position until the said cam 58 passes the outer ends of the extensions 61. When these arms hang at rest the projection 66 on the catch (it will be engaged by the edge of the ring 5-lof the hanger bar 51 and swung away from the pin 69, as shown by the position of the corresponding catch at the left in Sig. 4:. In this position the bent end 67 of the catch will clear the disk 87, so as to permit these two hanger bars 50 and 51 to be moved to the right as far as necessary. Then the cam 58 releases the hanger bars they will tend to return to their original position by their own weight and the weights i9. It will be seen from Fig. 5 that the cam 58 releases the bar 51 first, and the bar 50 next. As the bar 51 starts on its return movement the inner edge of the ringshaped section 5- of this bar will engage the inclined edge (58 of the hook (31 and lifts this hook to original position. The end 67 of the hook will now strike against the disk 87 and cause the return movement of the bar 50 to be arrested, even when the cam 58 moves past the element 75. The bars 50 and 51 therefore come into such relative position that the out-turned portions 56 and 57 remain apart long enough to permit the knob l to strike the bell a certain number of times to indicate the hour. The weights 9 on the hanger bars are properly designed with respect to the lower ends of the bars carrying the sleeves 62, the disks 63 and the hook 64.

Owing to the continuous rotation of the spindle 83 the disk 87 will be moved into such position as to bring the notch 88 (see Fig. S) in position to permit the bent end (37 of the catch (it to pass through the same. This will allow the bent end (37 to pass through the same. This will allow the hanger bar 50 to move back to its starting position, and the operation of striking the hour will then be completed, because the outturned ends 56 and 57 carried at the lower ends of the bars 50 and 51 will now be together again and in position to stop the bar 5 carrying the knob st before the knob reaches the bell 2. The bar 51 is finally stopped by that part of the disk 79 which carries the aperture receiving the pin 69, and when the bar 50 returns to original position the projection 66 will engage the ring 5% and move the hook (it away from the disk 87 and disk 89. Through the motion of the gear 83, which is driven from the main spring, the boss 77 will be turned, and therewith the sleeve 78. This will cause the disk 79 to be rotated, and through its engagement with the pin (39 to turn the disk (33. Preferably the direction of rotation of the gear 85 and disks 87 and 89 is the same as the direction of rotation of the disks 79 and 63, but the disk 79, and consequently the disk 63, are rotating slower. The speed ratio of the disks 87 and 79 will be such as to increase the space of time which intervenes between the instant when the end 67 engages the disk 87, and the instant when, after passing through the adjacent recess 88, this end 67 slips over the edge of the disk 89. The last ring always takes place when the catch is against the disk 89, and the slipping of the upturned end (37 of the hook over the edge of this disk allows the hangers 50 and 51 to come together at their ends 56 and 57. For example, when the parts of the clock are in position to strike for the first time the hour of one, the disk 7 9 will be in such position as to hold the disk (33 so that the end 67 will not engage the disk 87 at all when the bar 50 returns, but will pass directly through the recess 88 and be stopped by the disk 89. The disk 89 will hold the ends of the bars 56 and 57 apartlong enough to allow the knocker & to strike once, and after this single ring the end (37 slips off the radial edge of the disk 89 and further ringing is prevented. One hour later the disks 79 will have shifted the disk (33 so as to permit the end 67 to strike the disk 87 near the entering edge of the recess 88, so as to give the knob at a chance to strike once before the hook 67 passes into this recess, and once again before it slips off the edge of the disk 89. Thus the hour of two is indicated, and so on through the entire twelve hours, when the same operation is repeated.

The circumferential extent of the recess 88 is more than one-twelfth of the circumference, and the disk 89 for each of the disks 87 can be mounted on the element 86 so that it can be adjusted to bring its end into alinement with this recess in the proper position. The position of the elements in question is shown in Fig. 8.

The operation of the hanger bars 50 and 51 at the left in Fig. 4 is the same, only they regulate the knob 3 to strike the minutes. I preferably arrange the parts so that the knob 3 will strike once at five minutes after the hour; twice at ten minutes after the hour, and so on, so that the listener may ascertain by multiplying the number of rings by the numeral five, the number of minutes that have intervened since the last hour.

As seen in Fig. 4 of the drawings, the disk 63 at the right in said figure, carrying the hook (34, revolves once in twelve hours, while the corresponding disk (33 at the left in said ligure revolves once every hour. The notched disks 87 rotate at the same speed. 30th pairs of bars 50 and 51 are moved by the cams 58 an equal number of times per hour. The cams 58 move the pairs of bars alternately. The hour is struck first, and the minutes second, the hammer 4 striking the current hour for each minute during the hour, and the hammer 3 striking immediately afterward, to indicate that minute whose number is a multiple of live which is nearest to the present minute.

For convenience I ha shown the disk 87 on Fig. 8 marked into twelve equal divisions, the ur indicating the beginning of the arc constituting the first division being located substantially at the edge of the recess, but near the point 2 above referred to, and the mark indicating the twelfth di .ision being located in the recess 88 near the edge opposite he edge containing the point 1 that is to say, on the back plate 89. This is because the recess 88 is more than onetwelfth oi the circunrlierence, and if the first division begins at one edge of the recess, the last division will begin within the opposite edge of the recess.

Let us assume, for example, that, when the cam releases the hanger bars, allowing the same to swing apart, the inner edge of the ring 54 carried by the plate 51 engaging the inclined edge 68 of? the catch to force it toward the spindle 83, the bent outer end of this catch will strike the disk 87 at the point marked 1, which practically coincides with the point 2. The disk rotating in the manner described will hold the hanger bars and their ends 5i) and 57 apart long enough to allow ten rings of the hammer to take place before the recess 88 comes in position to allow the catch to slip through it, and when this happens the eleventh ring will be ivcn when the catch engages the point marked 12 on the plate 89. The tV-fGlTtll and last ring will occur when the catch, through the further movement of the disk and p re, is on the part 1 on the plate 8 after which the catch slips oii and allows the hanger bars 50 and and their ends 536 and to swing together. Further ringing is thus prevented. One minute later, "when the hour of twelve is to be again struck, the catch 64- will. strike the point' 'ed 2 on the disk 87, which is onesixt th of a division of the plate 87 distant from the point marked 1, and the twelfth ring will now occur when the catch is on the point marked 2" on the plate 89.

The catch 64 contacts with the disk 87 at the point 2, because the disk 79 has in the meantime shifted the disk 3 the required extent, moving it, as stated above, in the same direction as the direction of rotation of the shaft 83 on which the disk 87 is mounted. In this way, the hour will be struck sixty times between the hours of twelve and one, and by the time the instant arrives when the knob 4 is to strike but once to indicate that the hour of one has begun, the disk 3 will have been shifted to such an extent by the disk 79 that, when the cam releases the hanger bars 50 and 51, the end of the catch (it, owing to the relative posi tion of the disk 87. will pass directly through the recess and strike upon the back plate 89 at the point 1 Since, as above stated, the knob 4 will strike, owing to the associated arm 42 being in. position to slip off one of the teeth oi the gear 18 as soon as the arms are released the instant the ends 56 and 57 are swung apart, the ring to indicate that the hour of one has arrived will take place before the catch slips oil the edge of the back plate 89 adjacent the point marked 1. One minute later, owing to the disk 79 continuing to shift thedisk 63, the ends 67 of the catch will strike the back plate at the point 2, to ring the hour of one the second time, and this will take place sixty times until the knob 4 should strike the hour of 2. By this time the disk 79 will have shifted the disk 63 so as to make the catch engage the back plate about the point 12, and so on through the entire twelve hours.

It will be seen that the gear 85 has twelve teeth, and that when the disk 87 arrests the catch by contacting with the same at the point marked 1, so as to hold the hanger bars apart until the disk has moved into position to permit the catch to pass through the recess 88 and slip oil the edge of the back plate 89, nearly a revolution of the disk and the gear 83 takes place. This gear, as above described, intermeshes with the gear 18, and consequently when the gear 85 makes one complete revolution, the gear 18 moves twelve teeth to operate the bar 42, corresponding with the hammer 4, and makes the hammer 4 give twelve rings. Similarly, when thehour of one is to be struck, the bars 50 and 51 are held apart through not more than one-twelfth of a revolution of the disk 87, which is to say, one-twelfth of a revolution of the gear 85. Consequently, the gear 18 is moved so as to cause but one tooth to move the arm 42, and hence the knob 4 makes but one ring.

As stated above, every time the hour is struck the first ring takes place the moment the ends 56 and 57 swing apart. This is because the arms 42 will be so related to the teeth of the gear 18 that the arm 42 operating the hammer 4, is released by one of the teeth of the gear 18 the instant the ends 56 and 57 separate. This relation of the parts is necessary to prevent more than the necessarynumber of rings being given for each hour in the course of the hour; that is to say, while the disk 79 is shifting the disk 63 through the pin 60, so as to move the same into position to control the bars and 51 in such a way as to cause the succeeding hour to be properly struck when it arrives. For example, the first ring of the hour of twelve, when the hour of twelve is to be struck for the first time, takes place when the catch is on the point 1. The first of the hour of twelve, when the hour of twelve is struck the second time, takes place with the catch at the point 2, but during the entire hour, when the disk 63 is being shifted so that the catch contacts with the disk 87, successively at sixty different points between the points marked 2 and 1 on the disk 87, no more than twelve rings should be given. The last ring of the hour of twelve when it is struck the first time takes place the first time at the catch 1", and the last ring of the hour of twelve when it is struck for the last time just before the time arrives for striking the hour of one, that is to say, the twelfth ring, when the hour of twelve is being struck for the siXtieth time, will occur when the catch is near the point 12. From the point 1'2 to the opposite edge of the plate 89 near the circumference of the disk is not quite onetwelfth of the circumference of this disk, and this means that the gear 85 will move not quite the space of one tooth to move the disk 87 and the plate 89 this distance. The gear 18 will not move said wheel 85 quite the space of one tooth, after the twelfth and last ring of the hour of twelve.

Normally, the left disk 79 will turn once for each hour, and the disk 79 at the right once in twelve hours. Further, the cams 58 will turn once every two minutes, and the wheel 85 and disks 8? two times in one minute. The cams 58 and gear 18 are mounted so as to be adjusted on the spindle carrying them. Preferably, also, the gear 18 will have forty-eight teeth and the gear 85 twelve teeth, and the teeth on the other gear wheels will be in corresponding number, to secure the desired results. After one cam begins to act twelve teeth of the gear 18 pass before the next cam acts.

Referring to Figs. 13, 11 and 17, I employ a pair of blocks 91- mounted on pivots 95. T 0 these blocks are secured the arms 42 and the hammer arms 5. Each of these blocks carries an insulating sleeve 96 secured thereto, and through each sleeve passes a metallic conductor 97. The sleeves are mounted at the front and back of the framework 1 at the top of the same, and there are four mercury cups 98, two in front and two in. back, the conductor 97 at the back bridging the rear pair and the conductor 97 in front bridging the front pair. These sleeves and the conductors are rocked as the arms 4-2 are moved by the gear 18. and they will be in level position, forming a path between the pairs of cups controlled by them as their respective arms slip off the cogs to enable the knobs 3 and 1 to strike the bell 2. The front pair of cups will form part of a circuit containing a red lamp, and the back cups will form part of a circuit containing a white lamp. Consequently, when the hour strikes the red lamp will light. and when the minute strikes the white lamp will light up. The number of flashes will indicate the hour and minutes.

In the form shown in Fig. 15 I employ a block 91 mounted upon any form of pivot shown at 95, this pivot to be *arried by a bracket 9G is an insulating sleeve, and 97 a conducting member bridging a pair of mercury cups located at the front and back of the frame 1. From one of these cups leads a conductor to a white lamp 9!.) which is in circuit with a battery 100, this battery being connected to the bracket 15, which is preferably insulated from the framework at 4-5. This insulating plate -15 carries a contact shown at 122, from which leads a wire 101 to a rotating hub or sleeve 102 carried upon an insulating sleeve 103 on a journal 10 1-. This journal carries a gear 29 actuated by the gear train shown in Figs 1 to 4 inclusive. On this hub is rigidly secured a plate 10:"; having a notched upper end forming a voke to receive screws 106. These screws have counter-bored ends to receive the conical ends of a pin 107 which carries a projection 108. This pin is cut away on its lower side to form a square recess. and 109 is a bell-crank lever pivoted on the plate 105 at 110. One arm of the bell-crank lever is engaged by a spring 111 anchored to the plate 10:") by a screw 112, and at the other end of this arm is a projection 113, which engages the inner end of the recess in the pin 10?, to hold this pin in such position that the projection 108 will be vertical. This pin also has a horizontal projection 114;.

The spindle t3 which carries the actuating gear 85 is geared to a plate 115, to be turned therewith, but is insulated therefrom by a suitable bushing. This plate has a circumferential notch which is bridged by a segmental projection 116 carried at the end of an arm which is regulated by means of a screw 117, and pivoted to the plate 115 at 118. A spring 119 holds this arm against the regulating screw.

A third mercury cup shown at 120 is located between and beneath the cups 08, and in this cup dip the ends of a star wheel 19]. This wheel may be carried by a shaft which may be actuated at a constant speed by any mechanism and may carry the e of this shaft with the sleeve thereon c: rries the Wheels 19 and 23 as best seen in Fig. 1.5 oi the (hi; wings; and insulation 193 may 0 employed at this enrl also lo keep the sh t out oil? electri all contact with the hraekc;
